BACKGRULIND OF INYENTION
1 _ Field of the Invention ThE present invention relates generally to a connecting structure for check valve, and more particularly to a design with the valve base of the cheek valve and the pin hole of the water-blocking disk and the U-shaped base of its pin hole, and the U-shaped base and the pin hole are formed in one-piece, so that the degree of preciseness may be mare precise in a controllable scope for assembling water-blocking disk, as well as for the movement of the water-blocking disk.
2. Description of Related Art FICrS. 1 and 2 Shaw the perspective view of the current check valve and the operational view of its processed pin hale. The production of the conventional check valve uses rougher molding technology; first, it molds the shape of basic valve base 1, and its connecting surface, such as the terminal surface 3 of the protruding part 2of its valve base ~, and after that, it drills pin hale 5 on the _.
terminal surface 3 of the protruding part 1 by the drill bit 4, the location of pin hole 5 takes away the width of the location for the U~shaped base 21 of the water-blocking disk 20 As shown in FIG 4, after taking away the location for the U-shaped base 21 of the water-blocking disk 20, both sides inside the valve base must farm twa protruding parts b 7, and between the two protruding part 6 7 must have the width of the U-shaped base 21 for the water-blocking disk 20 that in the air, and after the drill bit drills one side of a protruding part 6, it creates the oscillating effect in the air, which can easily cause the pin hole expands in a cone fashion, on the other hand, the drill bit 4 must drill the .k~ole on the other side of the protruding part 7, however, because it is hard to find a correct pin hole 8 on a flat surface, and with the part of the drill bit hangs in the air, which may cause the hale 8 is drilled crooked, and makes it hard for these two holes S 8 to line up far the pin to go through.
As shown in FIC'x 4, the water-blacking disk 20 is more difficult, and it may cause the water-blocking disk become crooked in the future, and cause leakage, and it is being used in the location with high pressure, therefore, the leakage is easy to cause danger.
Thus, to overcome the aforementioned problems of the prior art, it would be an advancement if the art to provide an improved structure that can significantly improve the efficacy.
To this end, the inventor has provided the present invention of practicability after deliberate design and evaluation based on years of experience in the production, development and design of related products.
SUMMARY t~F THE I1VV'E1V'rI4N
1. The check valve may be formed in one-piece with the ear-like chip, its through hole, and the through hole of the protruding part to avoid extra ,process to improve the erect. Because extra processing can cause error in degree of the preciseness or waste the processing equipment and material, and it is time consuming. When the water-blocking disk is assembled 'with pin, the related positions may be more precise, the movement of the water-blocking disk may be z completed correctly and smoothly, and it would not have the problems such as being crooked, not closed anc~ leaking.
To sum up, the connecting structure for the check valve of the present invention uses one-piece forming by connecting the thraugh holes between the ear-like chips of the water-blocking disk to the valve base, so that the degree of preciseness of the ear-like chips inside the valve base and their through hales may reach the requirement of preciseness and avoid extra processing; and because of the degree of preciseness is high and it is assembled easily, so that the movement of water-blacking disk is more accurate, and the effect of check valve may be achieved. Therefore, it may be safe to use the check valve under the high pressure, and to have better practicability among the same type of products. The present invention qualifies for the requirement for patent and applies far patent accordingly.
Although the invention has been explained in relation to its preferred embodiment, it is to be understood that many other possible modifications and variations can be made without departing from the spirit and scope of the invention as hereinafter claimed.
